SARDINE

Generic plugin-based monitor, mainly for use with Xfce genmon

Generic plugin-based monitor, mainly for use with Xfce genmon.

SYNOPSIS

sardine [options] command [args...]

DESCRIPTION

sardine is a plugin-based "pretty-printer" that allows adding own sub-commands and use them with common interface.

Typical use case is when you have a space where only limited number of characters can be displayed, but you want to display arbitrary amount of information (like name of currently playing song or status of a task), either having it trimmed gracefully or defining own way how to "squeeze" it in.

Apart from that, the plugin can define other modes of output that might suit other targets better. For example, genmon Xfce plugin is able to periodically display output of a command in desktop panel. Apart from displaying simple string, it can parse XML-like content and use it to display tooltip or an icon. You could implement mode in your plugin for this target, and use sardine both for your Xfce panel and your terminal in a consistent manner.

OPTIONS

-c, --chars chars limit in charcters

--format format output format: plain for plain text, xgp for xfce4-genmon-plugin. User- defined format names must start with x- prefix.

-p, --plain same as --format=plain

-x, --xgp same as --format=xgp

-h, --help print help message

--version show version

EXAMPLE PLUGINS

These are pretty useless for real life, they only serve for illustration of basic concept or as examples of how to implement your own plugin.

sh

This one takes first argument as a command name and runs it as a new process, passing the rest of arguments to it untouched:

$ sardine sh uname -a
Linux fullmoon.brq.redhat.com 3.13.6-...
$ sardine sh who
somebody  tty1         2014-03-28 19:...

Note that arguments are untouched, so things like wildcards/globs will not work (unless the shell where you type the sardine command expands them).

echo

Connects the arguments and prints them:

$ sardine echo hello
hello
$ sardine echo "one two"   "three"
one twothree

dump

Dumps the arguments as Python sees them (using repr() builtin)

$ sardine dump "one two"   "three"
args = ['one two', 'three']
$ sardine dump uname -a
args = ['uname', '-a']
